@Kalamel I'm not in the field either but I found some articles, it seems like in general the teen pregnancy rate appears to have steadily decreased in the US but according to the CDC is still "substantially higher than in other western industrialized nations, and racial/ethnic and geographic disparities in teen birth rates persist."

This is arguably due to more comprehensive sex education (specifically not abstinence education) and much greater access to healthcare, planned parenthood especially, which provides both affordable education and relevant health services and I have heard is often the sole provider of said things in many parts of the country.
Here's a paper from 2011 that finds that "increasing emphasis on abstinence education is positively correlated with teenage pregnancy and birth rates. This trend remains significant after accounting for socioeconomic status, teen educational attainment, ethnic composition of the teen population, and availability of Medicaid waivers for family planning services in each state." and a second paper published in 2007 contains similar findings about abstinence-only education:

So as long as these social services--public education and healthcare--continue to be adequately funded then they can grow and improve, and teen pregnancy should continue to decrease. Unfortunately the past couple years Planned Parenthood has seen exactly that...sooo if you can vote in the USA please vote correctly, in the Democratic primaries too, for Bernie Sanders, also for Medicare for All, lol but rly tho
